The TR6 plugs are ideal for a nitrous LS1, but I wouldn't say they were ideal for an N/A LS1. That would most likely be the TR55 gapped at .055, depending on mods. Running the TR6s N/A will most likely lead to some fouling since their heat range is a bit too cold.

What kind of mods would the TR55s be good for? For instance, my car (see sig). Would TR55s, gapped at .055 be appropriate, or something else?

People use TR55s all they way up to a heads/cam setup. I know of a couple people that run a different plug with their heads/cam setup, but I'm not sure what they use. I think it might be the TR5.

I have similar mods to you, and have used TR55s for a long time.

I run the Tr6 and dont spray too much anymore and they always look great when i change them, never the slightest indication of fouling. If I were you just use the TR6 @ .035-.038.

Nope, they are copper, and cost about $2.00 each. I tried the expensive *** TR55 IR (Iridium) and they didn't help ****.

why does everyone like these plugs? do they make more power then delco platinums, or whatever comes stock? not that I put any miles at all on my car, but I take it being copper, you should change them much more often.....how often do you change them?

Why? They are cheap, and they work. I change mine about every 15-20k miles, but only because I'm **** like that. The gaps have never opened up on me.
